A Case of Intravenous Pyogenic Granuloma
Abstract
- Cooper at al and Mills et al asserted that the essential pathologic finding of pyogenic granuloma (PG) is a unique lobular organization of capillaries. This pathologic pattern is present not only in conventional cutaneous PG, oral-nasal PG but also rarely in intradermal PG, subcutaneous PG and intravenous PG. A 32-year-old man presented with a two-day history of an asymptomatic, movable, pea-sized nodule on his left forearm. Excision biopsy revealed a pink, oval, cyst-like nodule within the vein of the subcutaneous tissue of the medio-lateral aspect of the forearm. Histopathologic finding of the nodule showed rnultiple lobules of capillaries and the lumens of the capillaries were lined by normal endothelial cells. The nodule was connected with the venous wall by a thin stalk. Each lobule was separated and surrounded by fibrous stroma. There was no evidence of thrombi.
